¬_¬ yet another little tweak, annoyingly ive just found out that the monsol head/cressbrook road is closed for a cycle race. SO on your printed rout plan cross out all steps between Litton and Ashford (where the cricket field is). Here we may if needed go strait through Litton, turning right at the bottom of the road, then right again just before the abandoned petrol station, this will then eventual lead to Ashford where we pick up our original rout.

The Loo break will also need tweaking, this may now be in asford, so when coming down the hill into ashford, at the bottom of the road T junction, looking at a pub, turn right, then right again at the church, you will come to a small playing field with Loos. 
Sorry for the annoyance, James.
